IMPROVEMENT IN' SEEDING-MACHINES.

To ALLAWHOM 1T MAY ooNoEnN:

Be it known that we, ANDREW R. Ecctns'ros and CHARLES F. SWAIN, both formerly of Ripon, in the couiity of Fond du Lac, and State of Wisconsin, hat now of the city and county of Milwaukee, and State aforesaid, have inventedcertain new and useful Improvements in Sce ling-hIacliines, of which the following is a full, clear, and exact description, reference being had to the accompanyingdrawings, which make apart of this specicat-ion, and in which- 'i l Figure l represents a plan or top view of so much of our improved machine as is necessary to illustrate the invention herein claimed.

Figure 2 represents a vertical transverse section through the same, at the line :v 1; of tig. 1.

Figure 3 represents a plan view of the under side of the seeding-trough.

Figure 4 represents a front elevation of thc gearing.

The inventioniherein claimed consists in certain new and useful improvements, hereinafter set forth, on n seeding-machine, for which Letters Patent of the United States were granted to us, numbered 62,259, and dated February IO, 1867.

In the accompanying drawings, which show a Aconvenient arrangement of devices for carrying out the objects of our invention, two wheels, B B', are shown, as secured on .short independent shafts or stub axles, turning in suitable boxes underneath the frame A, which consists of a trough, having parallel sides, open at top and bottom, and divided by vertical transverse partitions into a series of cells, a, as shown in our former patent, above mentioned. A tongue, 0, projects from the front of this frame. The drag-bars D, which carry the plonghs D', are hinged to the rear under side of the frame, in the usual way, so as to play freely vertically, and are raised, lowered, or held in anydesired position by chains d, attached to a rock-shaft or windlass,E, operated by a hand-lever, F, and sector, F', provided with a spring-deten t, f, taking into a sector-rack, G, on the frame. It will bc observed that thelifting-chains d pass over the back of thoroller, whilethesector-cordf passes around the front of the roller. By this means the windlass nevolvcs in the direction shown by the arrow, when the lcvcr F is pushed back, and thus lifts the plonghs. This arrangement we have found to be very advantageous in practice, as by it the driver can throw his whole weight on the lever in lifting the ploughs. The attendant can also by this arrangement lift the ploughs when walking behind the machine. In the drawings,- the chains d are too long, for when the ploughs are in the ground theeatchfshould be in the forward notch of the sector'- rack. A seed-trough or hopper, H, is pivotcd to the frame nt the lower forward edge, by hinges 7L, so that it maybe thrown forward when necessary for access to the under side. The trough .has openings in its botto-m, over the cells a. Toothed or grooved fceding-cylindcrs, I, mounted on a shaft, s', rotate in these openings. The bottom of the hopper is composed of inclined surfaces 7L', sloping towards the feed-cups I. In our formerpatent these feed-cups were shown` as made narrower than the openings in which they revolved. We have found, by experience, that the grain was apt to get into the spaces thus left between the feed-cups and the sides of the `openings, and be bruised o`r broken. 'lo obviatethis di'lieulty, we make the cups broader across their faces than the openings in which tley revolve, and cover their ends with iianged shields or caps t", fig. 2, which keep the grain withi-n the cells of the cup, and thus prevent it from being injured. To regulate the feed, a gaugeplate, K, is arranged to slide cndwise in suitable guides, underneath 'the hopper, and is provided with triangular openings directly underneath the feed-cups I. The plate is inoved endwise by a set-screw, l'c, and regulates the quantity of grain sown by increasing or diminishing the area of the openings c. A shut-oil` slide, J, moves cndwise underneath the gauge-plate, and has holes in it corresponding with those in the gauge-plate, and is moved by a foot-leverhj, pivoted on the frame. The gauge-plate and slide-plate move in guides L, attached to the bottom of the trough, in such manner that the shrinking or swelling ofthe wooddoes not alcct their working properly. A reciprocating scatteringplate, L, (similar to` that shown in our former patent,) is arranged underneath the frame. A spur-wheel, M, revolves loosely on the axle with which it is locked, when desired, by a sliding clutch, m, moved by a lever, m', and drives acorresponding pinion, n, on the shaft t', which carries the feed-cups I. A bevel-wheel, N, on this same shaft, drives va corresponding pinion, o, on a vertical crankshaft, 0,' on the end of the' frame A. A crank-pin on lthis shaft plays in a. slot in the scattering-plate L,a.nd thus reciprocates it. It will be 4observed that the bevel-wheel N and pinion n are both ttached to the hopper.

rlhe latter can be lifted without removing the gears, which are disengaged from the driving-gear by being so lifted, and again thrown into-gear when the hopper resumes its normal position.

The operationV is afs-follows: The seed are placed in the hopper. As the machinemlvnnces, the gearing rotates th'e'feed-cups I, into which the grain falls, :rndis carried round and do'ppedthrongh the openings c in the gauge-plate, into the cells a, from which itescoposthrough the scattering-plate, which distributes it uniformly over the ground, when it is'covered hy the cultivator-teeth.

Unless otherwise described, the construction of our machine is similar to that described in our former patent. i

What we claim as our invention, land desire to secure by Letters Patent, isy 1. The combination, with the rotating feed-cups, of the overlapping stationary sockets or shields', substantially as set forth for the purpose described. I v

2. The combination of the feed-cups, the gauge-plate, and the chut-oli` slide', substantially as set forth.

' 3. The combination of the windlass, the hand-lever, and drag-bars, With'liftiug-chain's, arrcngediasfdescribed, whereby the plou'ghs are lifted by the backward movement of the 1ever, as set forth.

In testimony whereof we have hereunto subscribed our names. l
